DEVICE FOR CLEANING GUNSAND OTHER TUBES.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application tiled January 16,1907. Serial No. 352,611.

To all whom it may concern;

Be it knownthat I, FRANK M. BIGELow, a citizen of the United States,residing at Aneta,in the county of Nelson and State of North Dakota,have invented new and useful Improvements in Devices for Cleaning Gunsand other Tubes, of which the following is a specification.

This invention relates to cleaning rods designed for use in cleaning gunbarrels or other tubes, and has for its objects to provide acomparatively simple, inexpensive device of this character which inpractice will thoroughly clean and' polish the interior of the tube, onewherein the polishing member or head will readily conform to tubes ofvarying sizes or to tubes of tapered formation, and one in which thesections of the head will yield relatively, thus to obviate scratchingor otherwise marring the surface under treatment.

With these and other objects in view, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed'.

In the accompanying drawings: Figure l is a side elevation of a cleaningdevice embodying the invention. Fig. 2 is a detail view partly insection, the section be ing taken centrally and longitudinally throughthe polishing head. Fig. 3 is a'detail cross section taken on vthe line3 3 of Fig. 2.

Referring to the drawings, it will be seen that the device comprises asa whole a rod or shank 1 and a polishing member or head 2 having at itsrear end a reduced neck 3 threaded for detachable engagement with aninternally threaded socket in the form of a metal thimble 4 fixed on theadjacent end of the rod l, the rear end of which latter is provided witha non-circular bore or socket to receive the non-circular shank 5 of atool 6 provided with a secure engaging portion 7 and with`a longitudinalslot 8 to receive a cloth or other cleaning fabric. The. member or head2, which is bifurcated as shown to forma pair of relatively movablesections or jaws 9, has applied to the outer faces of said jaws acovering l0 of felt or other pliable fabric, while arranged between theforward ends of the jaws, which are longitudinally recessed at 11 toform guideways, is a bowed spring l2 attached at a point adjacent itslongitudinal center to one other jaw within the guideway 11, said springserving to maintain the jaws in spaced relation and to permit them toyield readily toward each other.

In practice, the devices may, by suitably compressing the jaws againstthe action of the spring 12, be introduced into a gun barrel or othertube and thereafter moved back and forth through the same, as will bereadily understood, it being noted in this connection that duringreciprocation of the tool the same is rotated for bringing the fabric 10into Contact with all parts of the surface to be cleaned. When in actionand for the purpose of removing rust or the like from the interior ofthe tube, a piece of emery cloth may be applied around the member orhead 2 or the fabric l0 may be moistened and coated with emery powder.

It isto be observed that in operation the jaws will move readily towardeach other, thus to act yieldably on the surface to be cleaned andfurther that thel sections 9 will assume a position to conform properlyto tubes of tapered formation.

When desired, a piece of cloth or other fabric may be entered throughthe slot 8 for use in wiping out the tube, while the portion 7 may bebrought into action for manipulating screws employed in connecting theparts of the gun mechanism. i

Having thus described my invention, what I claim is:

l. A device of the class described comprising a rod, a cleaning membercarried thereby and consisting of a pair of relatively movable jaws, anda bow-shaped leaf spring interposed between said jaws and rigidlysecured to` one of them.

2. A device of the class described comprising a rod, a cleaning membercarried thereby, said member being bifurcated to provide a pair ofrelatively movable jaws, a pliable covering applied to the outer facesof the jaws, and a pressure spring interposed between the latter andsecured to one of the jaws and movably engaging the other.

3. A device of the class described, comprising a rod, a cleaning membercarried thereby and consisting of a pair of relatively movable jawsprovided on their inner faces with guide grooves, and a pressure springinterposed between the jaws within said grooves.

In testimony whereof, I aix my signature in presence of two witnesses.

FRANK M. BIGELOW.
